To explore the relationship between mental health of left-behind middle school students and awareness of mental health.Using cluster sampling method to select 428 left-behind middle school students in Jinan, using the mental health scale of middle school students and self-compiled mental health cognitive attitude questionnaire.We found left-behind middle school students' mental health level of force, paranoia, hostility and interpersonal sensitivity, depression, anxiety, learning pressure, maladjustment, mood swings, the psychological imbalance and total score were significant difference compared with the norm of middle school students (t = 10.67, 3.86, 3.78, 7.54, 2.51, 10.18, 8.79, 3.54, 6.56, -2.13, 6.83, P < .05). The top 5 detection rates of psychological moderate health problems are learning stress, anxiety, force, emotional instability and interpersonal sensitivity. There were significant differences in the scores of left-behind middle school students with different awareness of mental health knowledge (F = 4.880, P < .01) and emotional instability (F = 4.51 4, P < .05). The awareness of mental health knowledge was significantly negatively correlated with the total score of mental health, hostility, interpersonal sensitivity, maladjustment, emotional instability, and psychological imbalance scores. (r = 0.135, 0.182, 0.194, 0.189, -0.2, 0.124, P < .05).Left-behind middle school students' psychological health status is poorer, and closely related with the awareness of the knowledge on mental health; to improve the level of cognitive evaluation of left-behind middle school students on mental health is expected to improve their psychological health.
